INVENTOR. EDWARD GRUNWALD 235. BY l Arran/5V United States Patent C 3,0l0,ll4l SET-IN INSERT BINDER FOR FLOOR COVERIN GS Edward Grunwald, 134 W. 58th St., New York, NX. Filed Dec. 4, i959, Ser. No. 857,349 l Claim. (Cl. 16-16) This invention relates to protectors for door coverings and more particularly to -a binder bar for binding adjacent strips of iioor covering.

A principal object of the present invention is to provide a bar that binds and protects the edges of carpet material on floors.

Another object is to provide a binder bar with a channel of dovetail formation for the reception of a removable strip of iinishing material, the sealing strip serving to conceal a substantial portion of the bar and to leave exposed to view only the longitudinal` edges of the bar.

A specific object is to provide a substantially flat binder bar for effectively binding adjacent strips of carpet or linoleum to a supporting surface, said bar having means for supporting an ornamental facing strip over the joint between said strips.

Another object of the invention is to provide a door covering protector of this kind that is simple and rugged in construction, easy to install, pleasing in appearance and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description `and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a top perspective View of a fragment of a hinder bar for a floor covering embodying my invention, with a facing strip shown partially inserted, parts being broken away.

FIG. 2 is an enlarged top plan View of a fragment of a binder bar embodying the invention shown applied over a joint between two dierent kinds of oor covermg.

PEG. 3 is a cross-sectional View taken on the line 3-3 of FiG. 2.

FIG. 4 is a view similar to FIG. 3 showing the binder bar applied to one strip of lloor covering only.

FIG. 5 is a View similar to FIG. 3 but showing the floor covering on a concrete door.

FIG. 6 is a view similar to FIG. 4 showing the binder bar applied to one strip of a diiferent type of Hoor covering.

iFIG. 7 is an enlarged fragmentary view of the right hand end of FIG. 6, the facing material being shown in full lines.

Referring in detail to the drawings, a binder bar embodying the invention isV shown and designated generally by the reference numeral it). The binder bar consists of an elongated one-piece body or strip 12 of rolled, cast or extruded material, such as chromium, aluminum, yellow or white brass or like material adapted to bind a strip of carpet or the like to a supporting surface. The -body is substantially flat with its top side 14 llat throughout its length and width, The body of the bar, however, on its bottom side 16 along one long edge thereof, is thinned out to form a tapering portion 18, tapering upwardly and outwardly from a point inwardly of said long edge to said elongated side edge of the body as viewed in FIGS. 1 and 3. The elongated side edge of the body adjacent the tapered portion i3 is formed with an upwardly and inwardly turned flange portion 22 for the length thereof, the flange portion being provided with an inclined smoothly curved face 24.

Patented Nov. 28, 1961 On its opposite long edge, the body is formed with an enlargement 26 extending the length thereof and is substantially twice the width of the flange portion 22. The enlargement is inclined to the plane of the body of the bar as seen in FIG. 1 and has a smoothly curved outer surface. The enlargement at one long edge extends above the plane of the body of the bar and inwardly of its adjacent long edge thereby providing an upper flange portion 28. The upper ange portion has an inner inclined plane face 30. The enlargement also at its other long edge extends below the plane of the body and outwardly of its adjacent long edge thereby providing a lower flange portion 32 with an inclined plane inner face 34. Flange portion 32 terminates along its lower edge in a beaded portion 36. The flange portion 22 and the upper ange portion 28 dene between their respective faces 24 and 30, a channel 38. The side edge wall of the channel constituted by flange portion 22 has a slanting surface continuing into a straight surface, and the opposed side edge Wall of the channel has a similar slanting surface continuing into a straight surface. A plurality of holes 40 is spaced along the center of the `body of the bar for receiving fastening elements such as screws 42 and the like.

In FIGS. 2 and 3, a portion of a wooden floor 44 is shown covered with a strip of linoleum 46 and a strip of carpet 48, a cushioned lining or pad 5t) being shown under the strip of carpet. A bar 10 is shown binding the strips together. The bar is shown disposed along and over the long edge of the carpet strip 4S with its long ilanve 26 extending over and clamped against the long edge of the linoleum. The 'bar is shown in straight flatwise condition over the floor covering and is fastened to the floor 44 by the screws 42 passing through the holes 40 in the bar l0 and through the carpet and pad into the floor. The pressure of the bar tends to squeeze the superimposed long edges of the carpet strip and pad reducing the thickness thereof whereby the inclined lface 18 of the flange 22 seats on the inclined portion .of the carpet strip bringing the b-ody of the bar into a flat condition and positioning the ange 26 so that its bead presses against the linoleum 46 and so that its outer surface curves upwardly and inwardly as shown in FIG. 3.

A strip 54 of facing material such as linoleum having beveled top edges 56 is removably inserted in the channel 38 and is held in place by the flanges 22 and 26 for finishing off the binder bar.

The binder bar lil in FIG. 4 is shown clamping a strip of carpet 4S against a wooden floor 44. The body l2 of the binder bar is pressed over the edge of the strip 4S with its flange 22 pressing against the pile of the carpet.

In this situation, the bead edge 36 of the ange 26 presses directly against the wooden floor 44. The screw 42 secures the binder bar in clamping position.

In FIG. 5, the linoleum 46 and carpet 48 lare shown covering a Aconcrete iloor 60. The linoleum is supported by a thick strip of plywood 62 and the carpet is cushioned by a relatively thin pad 64. The binder bar 10 is shown with the major portion of its body disposed over the linoleum 46 and the beaded edge 36 of the flange 26 pressing tightly against the carpet. The slanting face 18 of the flange 22 is shown clamped against the long edge of the carpet 48. The binder bar is fastened to the floor by screws 42 extending through the holes 40 in the bar and through the plywood strip 62 into the floor. The bar is positioned truly horizontal with its facing strip S4 exposed.

FIG. 6 shows the binder bar 16 clamping a strip of linoleum 46 to the wooden floor 44. A strip of plywood 64 is shown underneath the linoleum. The body l2 of the binder bar is pressed over the edge of the plywood with its ange 22 pressing against the edge of the linoleum.

The beaded edge 36 of the ange 26 presses directly against the wooden oor 44. The screw 42 secures the plywood and binder bar to the wooden oor.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit -myself to the precise construction herein disclosed and that Various changes and modifications may be made within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent A binder bar for overlying a joint between adjacent spaced strips of carpet with a cushioned pad thereunder and of linoleum with a plywood base thereunder, said binder bar comprising an elongated one-piece flat metal body rectangular in plan, enlargements on the long edges of the body constituting flanges along the long edges, the enlargement on one long edge and the body 4being cutaway providing a surface slanting slightly upwardly from the plane of the bottom surface of the body, said enlargement having a curved outer surface and having a at slanting inner surface terminating in a surface perpendicular to the plane of the body; the enlargement on the other long edge having a curved outer surface with an extension along its bottom edge, said extension having a downwardly slanting bottom surface with a beaded bottom edge below the plane of the body, said latter enlargement hav- 5 ing a slanting inner and downward surface terminating in a. surface perpendicular to the plane of the body; the inner slanting surfaces, perpendicular surfaces and top surface of the `body defining a channel, said body having a series of holes along the center thereof, and fastening 10 elements passing through the holes and through the plywood base and through a iioor below the base.
